Limbaugh — the big flash at the end of the life of the GOP?

Rush Limbaugh has gotten even bigger since the Barack Obama win last November, possibly due to his very public wish for the new President to “fail.” He’s achieved powerhouse status within the GOP, seemingly due to his percieved sway over the party’s base.

Here’s a recent Vanity Fair analysis. It’s long, but it’s worthwhile to read on the way to this penultimate point:

The dirty little secret of conservative talk radio is that the average age of listeners is 67 and rising, according to Sinton—the Fox News audience, likewise, is in its mid-60s: “What sort of continuing power do you have as your audience strokes out?”

Is the Axis of Rush is losing its grip on the American public? We’ll know before long.
